Cycloplegia is paralysis of the ciliary muscle

of the eye, resulting in a loss of accommodation. Because of the paralysis of the ciliary muscle, the curvature of the lens can no longer be adjusted to focus on nearby objects.

What is the purpose of Cycloplegic agents?

Anesthesia for Ophthalmic Surgery

The cycloplegic agents act via parasympatholytic action to block the muscarinic receptors of the ciliary body, paralyze the ciliary muscles, and inhibit accommodation.

What is a Cycloplegic effect?

Cycloplegia is the paralysis of the ciliary muscle of the eye resulting in dilatation of the pupil and paralysis of accommodation. This can be achieved by instilling cycloplegic agents such as atropine, cyclopentolate, and tropicamide into the conjunctival sac.
